Cayenne pepper cranks the sauce up to 800 Scoville units of heat compared to Taco Bell's Fire Sauce at 500 Scoville units, which makes this the hottest stuff you can get at the chain. Now, with this secret formula, you can adjust the heat up or down to your preference just by playing with the amount of cayenne you add.
Though Tabasco's peppers come from the savagely spicy species Capsicum frutescens, the sauce isn't actually all that hot. It comes in between 2,500 to 5,000 on the Scoville Heat Unit Scale, and that's in the lower half. You can do a lot more damage with a few hits of, say, Melinda's Naga Jolokia sauce.
